The development team behind REPO appreciates the community of players and modders but reminds modders to optimize their creations to maintain server stability. They expressed concerns about mods that increase the player count beyond the default limit of six, which can strain servers, similar to issues faced by other indie games like Content Warning. The team hopes modders will avoid creating disruptions due to limited resources. While larger teams can enhance excitement, they can also lead to chaos in gameplay and communication. However, there are many creative mods that do not strain server performance, such as the MoreHeadPlus mod, which offers cosmetic enhancements for robots. The developers encourage a balance between creativity and performance to ensure a positive experience for all players.
